Upgrading from .net framework v1.1.4 to a later version

Hi

I've just taken over the administration of a web server, Windows server 2003 IIS6.

Since it was installed the .net framework has never been upgraded so it is still V1.1.4.

If I install/upgrade to V2 or better, will this impact the webpages currently running in any way.

I've read the below article and it states that if the .net V2 is installed it will create a new folder and does not touch the current installation, therefore the applications and websites currently using V1.1.4  will still continue using it.

I would like to upgrade this due vulnerability issues.

.NET Framework doesn't get "updated" in the traditional sense. Each version you install is its own installation and doesn't usually effect the previous.

You can have all the different version (1.1, 2, 3, 4) installed and still run different web sites using different version. All that can be configured through IIS.

Thanks tobyweston,

If I switch to V2 will this effect the current web pages.

It shouldn't effect the way the page runs, the .NET frameworks usually adds functionality instead of removing it.

Installing a hotfix like the one you mentioned should see no problems at all.

Best thing to do is change it and test all of the site to make sure its not affecting anything. If you have it in a test environment too this can be helpful to check with.
